Numerical analysis of heat extraction efficiency in a multilateral-well enhanced geothermal system considering hydraulic fracture propagation and configuration

•Exploitation of deep geothermal energy in a multilateral-well EGS was studied.•A 3D THM coupled numerical model was proposed and implemented.•Thermal conduction and convection in both pore and fractures were considered.•Creation process of hydraulic fractures on heat extraction performance was stud...
